Thus you shall eat it: with a belt on your waist, your sandals on your feet, and your staff in your hand.
You shall eat it in haste. It is the Lord’s Pascha.
For I will pass through the land of Egypt on that night and will strike all the firstborn in the land of Egypt,
both man and beast; and against all the gods of Egypt I will execute vengeance:
I am the Lord.
Now the blood shall be a sign for you on the houses where you are;
and when I see the blood, I will pass over you;
and the plague shall not be on you to destroy you when I strike the land of Egypt.
(Exodus 12:11-13)
